Chinese Discourse Coherence Automatic Analysis Method Study

With the continuous development of natural language processing technology, Textprocessing technology aroused people’s concern further, such as information retrieval, textclassification, automatic generation of text, and so on.These technologies can make our workmore easy and quick.But, in the practical application, the processing result of thesetechnologies is unreliable on a certain degree.For example, in the process of automaticgeneration of text, many paragraphs of text are incoherence due to restrictions of thealgorithm. But because the length of generated text is too big, people can not be quick forhuman identification. if there is a kind of technology to evaluate the coherence in the textautomatically after the texts are generated, we can can make the generated text more smoothand more practical. In addition, in the process of deep process related the field of naturallanguage process, the situation that the result of the experience is not correct because there isno guarantee for the coherence of the corpus in the pretreatment stage often occurs.To solve these problems, this paper puts forward the subject that Chinese discoursecoherence analysis. The research of the subject is based on the four necessary conditions ofdiscourse coherence:there is a conceptual relationship at least between sentences, Thesentence sequence in the discourse must conform to the logic, the theme and rheme in thediscourse must connect with each other, the involved topics in the discourse must havecorrelation. At first, analyze Chinese discourse coherence around one of the conditionsrespectively. Finally, integrate the four solution and then comprehensively analyze Chinesediscourse coherence from multiple aspects. In this paper has done the research and putforward the corresponding solutions based on the two aspects that there is a conceptualrelationship at least between sentences and the theme and rheme in the discourse mustconnect with each other. based on the final the result of experiment. To a certain extent, thesolution that this paper puts forward can analyze the coherence of sentences in discourse. Butto get the more accurate analysis results, we must integrate these four aspects to analyze thesubject.
